摘要：It is well known that controller design is often unavoidable for extreme and zero stability, and that unstable poles (zero) limit the performance of the controller. In this paper, we study the limit zeros and poles of the discrete-time model where the sampling period tends to zero in the case of zero-order hold (ZOH) or generalized sampling-data hold function (GSHF).We first introduce GSHF and give its transfer function. Then we discuss the distribution of zero polarity with discrete time systems using ZOH or GSHF, and give their stability behavior. When the GSHF is used for signal reconstruction, the stability of the limit zero of the discrete-time system can be significantly improved and a discrete-time design with a stable zero in the case of GSHF is given.
